  "prompt": "A stark, high-contrast abstract composition in a square 1024x1024 format. The dominant imagery should evoke a sense of confinement and existential dread. Imagine a single, harsh, jagged line resembling a broken wall or a fissure, rendered in deep, oppressive black. This line should bisect or fragment a field of muted, desaturated grey, almost a concrete texture, suggesting a stark, unyielding environment. Subtle, almost imperceptible, hints of deep, shadowy indigo or a faded, bruised purple could bleed into the grey, adding a melancholic undertone. The lighting should be dramatic, with sharp contrasts between light and shadow, creating a feeling of isolation and introspection. The overall mood should be somber, intellectual, and slightly unsettling, conveying the psychological weight of the themes. The aesthetic should be modern, minimalist, and powerfully evocative of philosophical depth, suitable for a literary and thought-provoking audiobook cover.",
